If you've ever tried to do a voice acted game in AGS you'll know that it takes a lot of work and its very fiddly keeping track of sound files. Even if you've only use music or sound effects in AGS, you'll know that its not AGS's most friendly aspect.
Well, in AGS 3.0, there is an great editor plugin (that's a plug in for the Editor, rather than the engine, so you don't need to worry about Linux compatibility issues, etc.) which makes managing audio files much easier. You can find details in the Tech forum thread about the Audio Manager Plugin.
It's also worth noting that these fabulous editor plugins are really taking off with AGS 3.0. In 2.72 they were theoretically possible, but none of them really worked properly. In AGS 3.0, they are noe fully supported and coming into their own. Lemmy and Binky (of The Forgotten Element) are putting together an all-singing all-dancing one called AGX which will be worth looking out for, too.
